Novel weft accumulator of water-jet/air-jet loom

Abstract

The invention relates to a novel weft accumulator of a water-jet / air-jet loom. The weft accumulator used for storing and transporting weft yarns comprises a shell, a weft storage-control electric motor, a weft drum, a weft-releasing body, a weft-placing coil, an electromagnetic needle and a weft-winding shelf, wherein the weft storage-control electric motor is installed on the shell to connect theweft-winding shelf and drive the weft-winding shelf to rotate; the weft-releasing body is arranged on the weft-winding shelf, and the weft-releasing body is obliquely arranged in the axis direction near the weft-winding shelf; the weft yarns wind the weft-releasing body and the weft drum at intervals; and the electromagnetic needle is also disposed on the shell and the electromagnetic needle is placed above the weft-placing coil to control the releasing and the stop of the weft yarns. The novel weft accumulator of the water-jet / air-jet loom is simple in structure and convenient to use, and the yarns are in interval distribution so as to avoid twining; and damage of weft yarns is minimized owing to the shorter contact length between the weft yarns and the weft drum by setting the weft-releasing body.

Description

【Technical field】 [0001] The invention relates to a composition device of a water-jet / air-jet loom, in particular to a novel weft feeder of a water-jet / air-jet loom, which belongs to the technical field of textile machinery. 【Background technique】 [0002] The weft feeder is a device for processing weft yarns on textile machinery. When the loom is working, due to the fast running speed of the weft yarn, it is easy to break the yarn directly from the yarn ball, thereby affecting the production efficiency. The function of the weft feeder can quickly wrap a certain length of yarn around itself. On the winding frame, it can be released at a very fast speed when needed, so as to increase the weaving speed and reduce the breakage rate. [0003] Existing (water jet / air jet) loom weft feeders are divided into mechanical weft feeders and electronic weft feeders. Among them, the fixed length of the mechanical weft feeder is realized by a fixed length wheel that is synchronized with ...

AI Technical Summary

Problems solved by technology

The roller type runs smoothly and has little damage to the weft yarn. The disadvantage is that the mechanism is complicated

The vibrating type is the mainstream weft feeder at present and has been widely used, but the existence of the vibration source has a non-negligible impact on the working life, noise and damage to the weft yarn of the weft feeder
